Description
Technical field
The present invention relates to field of automobile parts and components, and in particular to a kind of adjustable rear axle bushing of rigidity for adjustment.
Background technique
Back bushing set is used for the junction of rear overhang rack and vehicle body, and rigidity is the main performance of torsion girder-like rear suspension
One of parameter, therefore the rigidity adjustment of rear axle bushing is an important process of torsion beam type suspension adjustment.Traditional back bushing
Set rigidity adjustment usually makes a variety of different-stiffness and the bushing of structure is verified on real vehicle respectively, needs to make multiple sets of molds
And repeated disassembled and assembled bushing is needed, cause cost largely to waste, and extend the period of design instruction.
Summary of the invention
The purpose of the present invention is to propose to a kind of adjustable rear axle bushing of rigidity for adjustment, rear axle bushing manufacturers
Just, at low cost, and there is biggish stiffness tuning range, design cost can be effectively reduced and shorten the design cycle.
The adjustable rear axle bushing of rigidity for adjustment of the invention from skeleton and removably with the rigidity with skeleton
Adjusting block is constituted, and the skeleton is equipped with several accommodating holes, and the axis of accommodating hole is parallel to the axial direction of skeleton；The accommodating hole is extremely
It is few open at one end, for placing the stiffness tuning block.
In rear axle bushing rigidity calibration procedures, repeated disassembled and assembled rear axle bushing is not needed, need to only replace different number or not
Stiffness tuning block with material is the adjustment scheme of a variety of different-stiffness of can reach, save expense in calibration procedures and period at
This.
Specifically, the skeleton is made of the interconnecting piece of inner ring body, outer ring body and connection inner ring body and outer ring body, described
Cavity between inner ring body, outer ring body and interconnecting piece is the accommodating hole.Inner ring body, outer ring body not only can be with rigidity of fixation tune
Locking nub, it can also be ensured that contact friction force is consistent between each position of rear axle bushing and rear axle.
Further, the stiffness tuning block and accommodating hole are interference fit, and the end of stiffness tuning block is equipped with vertically
In the protrusion of stiffness tuning block axial direction, the protrusion of stiffness tuning block is exposed to outside accommodating hole.The mode of above-mentioned interference fit and
The protrusion of stiffness tuning block can be such that stiffness tuning block is stably bound in together with skeleton, prevent stiffness tuning block from accommodating hole
Middle abjection.
Further, the section of the stiffness tuning block is to fan arc, between stiffness tuning block adjacent in this way and different
Stiffness tuning block is identical to the pressure between skeleton, more meets the mechanical analysis situation of true bushing.
Further, which further includes inner and outer tubes, and the skeleton is located between inner tube and outer tube, skeleton
It is interference fit with inner tube, outer tube.Inner and outer tubes cooperation, for the limit to skeleton so that each position of skeleton by
The active force applied to rear axle all tends to be identical.
Further, for convenient for by outer tube, inner tube and Skeleton assembly, together, one end of the outer tube is equipped with outward bending
Flange；The length of said inner tube is greater than the length of skeleton and outer tube, and above-mentioned flange and longer inner tube all can serve as stress
Position is to assemble inner and outer tubes.
Further, the inner ring body, outer ring body, inner tube, outer tube are to be arranged concentrically, and such stiffness tuning block is in skeleton
The stress condition in portion is all almost identical, and the rigidity Design about rear axle bushing is also just more accurate.
Rigidity for the adjustment of the invention adjustable rear axle bushing design stiffness tuning block that can be dismounted, using not
The stiffness tuning block combination of same hardness, material and quantity, it can reach the rigidity adjustment demand of rear axle bushing, without simultaneously
Designing multiple rear axle bushings reduces development cost so as to shorten the development time of rear axle bushing.

Specific embodiment
It is for example related each to a specific embodiment of the invention by the description to embodiment below against attached drawing
The shape of component, construction, the mutual alignment between each section and connection relationship, the effect of each section and working principle etc. are made into one
The detailed description of step.
Embodiment 1:
As shown, the adjustable rear axle bushing of the rigidity for adjustment of the present embodiment is by inner tube 1, outer tube 2,3 and of skeleton
The stiffness tuning block 4 removably cooperated with skeleton 3 is constituted, and middle skeleton 3 is located between inner tube 1 and outer tube 2, skeleton 3 with
Inner tube 1, outer tube 2 are interference fit；One end of outer tube 2 is equipped with the flange 21 of outward bending；The length of inner tube 1 is greater than skeleton 3
And the length of outer tube 2, in order to which outer tube 2, inner tube 1 and skeleton 3 are assembled together.
Skeleton 3 is made into integration by rubber material, specifically includes inner ring body 31, outer ring body 32 and connection inner ring body 31 and outer ring
The interconnecting piece 33 of body 32 forms the cavity of several both ends opens, the cavity between inner ring body 31, outer ring body 32 and interconnecting piece 33
As for placing the accommodating hole 34 of stiffness tuning block 4, the axis of accommodating hole 34 is parallel to the axial direction of skeleton 3.It is inner ring body 31, outer
Ring body 32, inner tube 1, outer tube 2 be arranged concentrically, the shape of each stiffness tuning block 4 is identical, section be fan arc, cavity with
The central axes of skeleton 3 are that the center of circle is uniformly distributed in skeleton 3, and between stiffness tuning block 4 adjacent in this way and different-stiffness is adjusted
Block 4 is identical to the pressure between skeleton 3, more meets the mechanical analysis situation of true bushing.
It, can be according to specifically needing for stiffness tuning block 4 to be fitted in accommodating hole 34 in debugging, i.e. stiffness tuning block
4 with accommodating hole 34 be interference fit.In the present embodiment, the both ends end of stiffness tuning block 4 is equipped with perpendicular to stiffness tuning block 4
Axial protrusion 41, the protrusion 41 of stiffness tuning block 4 are exposed to outside accommodating hole 34, and inside and the skeleton 3 of protrusion 41 offset.Rigidity
